It's a "barely digital" standard.

It doesn't have any error detection or correction. The timing of the signal is still based on CRT TV's.

Really the whole lot should be done away with and replaced with something properly bidirectional, and preferably IP based so it can be routed anywhere.

I think DisplayPort done away with this legacy and uses packetized transmission.

Packets that still have to encode and adhere to strict VGA timings (Hsync/Vsync/blanking), and you arent allowed to send anything useful between the packets unless its a blanking period.
